It is generally believed that pursuit eye movements are unaffected by cerebellar cortical atrophy or cerebellectomy. The present study was performed on patients who underwent partial vermis and hemisphere ablations as a result of severe cranial injury or cerebellar tumors. Eye movements were measured by DC electro-oculography. A clear disparity of the slow phase of the optokinetic nystagmus was observed. When eye movements were contralateral to the ablated side the slow phase of optokinetic nystagmus was statistically slower than drum or visual field velocity. It is suggested that the cerebellum network is involved in the mechanisms of the smooth pursuit movement.
一般认为，追踪眼动不受小脑皮质萎缩或小脑切除的影响。本研究是对因严重颅脑损伤或小脑肿瘤而接受部分蚓部和半球切除的患者进行的。眼动通过直流眼电图进行测量。观察到视动性眼球震颤慢相存在明显差异。当眼动与切除侧对侧时，视动性眼球震颤的慢相在统计学上比鼓或视野速度慢。提示小脑网络参与了平稳追踪运动的机制。
